If NO is coded as 210, NOT is coded as 4200 and NOTE is coded as 21000, then how is NOTES coded?

If NO is coded as 210, NOT is coded as 4200 and NOTE is coded as 21000, then how is NOTES coded?
  1. 399000
  2. 420000
  3. 440000
  4. 630000

Solution

Using letter positions: N=14, O=15, T=20, E=5, S=19. NO: $14\times15 = 210$. NOT: $15\times20\times14 = 4200$. NOTE follows the pattern giving 21000. Following the established multiplicative pattern with the letter values of NOTES, the code is 399000.
